Vivek b8548439b7 [mellanox] Update SAI to SAIBuild2311.25.0.36, SDK/FW to 4.6.2104/2012.2104 (#17131)
Why I did it
Update SDK/SAI and FW for Mellanox Platform

How I did it
Update SDK/FW to v4.6.2104/v2012.2104

Fixed Issues:

Some of the Warmboot related files which were created by SDK during switch create are now generated during pre shutdown flow
New Features:

Debian 12 and kernel 6.1 support
Update SAI

New Features:

Auto Fec Support
FDB entries are now restored after warmboot to prevent temporary system flooding.
Minor Enhancement and Bug Fix in integrate-mlnx-sdk

How to verify it
Build Image and run tests
